Is the result more accurate when using decimals?
Yes, using decimals increases the precision of the conversion result, allowing you to express fractions of a smaller than one day, which is helpful in scientific or financial contexts.
What happens if I enter a negative number of days?
Negative days represent negative durations or times before a reference point. The conversion formula still applies, resulting in a negative value in a, indicating a time before the zero point.
